Subfault: 31.6
Description: Temperature model prewarning – motor1
Response: Thermal motor protection 1 – prewarning threshold
Cause Measure
Temperature signaled by temperature model of
motor1 exceeds prewarning threshold.
Check for motor overload.
Subfault: 31.7
Description: UL temperature monitoring
Response: Output stage inhibit
Cause Measure
Temperature model of active motor signals over-
temperature.
Check for motor overload.
Subfault: 31.8
Description: Communication timeout temperature sensor – motor1
Response: Output stage inhibit
Cause Measure
Communication with temperature sensor is dis-
rupted, e.g. via MOVILINK
®
DDI.
Check the cabling.
Subfault: 31.9
Description: Temperature too low – temperature sensor – motor1
Response: Warning with self-reset
Cause Measure
Temperature signaled by temperature sensor of
motor1 below -50°C.
– Check if a KTY temperature sensor is installed
in the motor but the parameterization has been
carried out for a Pt1000 temperature sensor.
– Heat the motor.
Subfault: 31.11
Description: Temperature sensor wire break – motor 2
Response: Application stop + output stage inhibit
Cause Measure
Connection to temperature sensor of motor2 in-
terrupted.
Check the temperature sensor wiring.
Subfault: 31.12
Description: Temperature sensor short circuit – motor2
Response: Application stop + output stage inhibit
Cause Measure
Short circuit in connection with temperature
sensor of motor2.
Check the temperature sensor wiring.
